Convergent Incremental Potential Contact
Minchen Li, Zachary Ferguson, Teseo Schneider +5
Recent advances in the simulation of frictionally contacting elastodynamics with the Incremental Potential Contact (IPC) model have enabled inversion and intersection-free simulati…
Topology Optimization with Frictional Self-Contact
Zeshun Zong, Xuan Li, Jianping Ye +5
Contact-aware topology optimization faces challenges in robustness, accuracy, and applicability to internal structural surfaces under self-contact. This work builds on the recently…
Mixed Variational Finite Elements for Implicit, General-Purpose Simulation of Deformables
Ty Trusty, Danny M. Kaufman, David I W Levin
We propose and explore a new, general-purpose method for the implicit time integration of elastica. Key to our approach is the use of a mixed variational principle. In turn its fin…
Affine Body Dynamics: Fast, Stable & Intersection-free Simulation of Stiff Materials
Lei Lan, Danny M. Kaufman, Minchen Li +2
Simulating stiff materials in applications where deformations are either not significant or can safely be ignored is a pivotal task across fields. Rigid body modeling has thus long…
Codimensional Incremental Potential Contact
Minchen Li, Danny M. Kaufman, Chenfanfu Jiang
We extend the incremental potential contact (IPC) model for contacting elastodynamics to resolve systems composed of codimensional DOFs in arbitrary combination. This enables a uni…
Hierarchical Optimization Time Integration for CFL-rate MPM Stepping
Xinlei Wang, Minchen Li, Yu Fang +5
We propose Hierarchical Optimization Time Integration (HOT) for efficient implicit time-stepping of the Material Point Method (MPM) irrespective of simulated materials and conditio…
Neural Re-Simulation for Generating Bounces in Single Images
Carlo Innamorati, Bryan Russell, Danny M. Kaufman +1
We introduce a method to generate videos of dynamic virtual objects plausibly interacting via collisions with a still image's environment. Given a starting trajectory, physically s…
Bounce and Learn: Modeling Scene Dynamics with Real-World Bounces
Senthil Purushwalkam, Abhinav Gupta, Danny M. Kaufman +1
We introduce an approach to model surface properties governing bounces in everyday scenes. Our model learns end-to-end, starting from sensor inputs, to predict post-bounce trajecto…
Metamorphs: Bistable Planar Structures
Gaurav Bharaj, Danny Kaufman, Etienne Vouga +1
Extreme deformation can drastically morph a structure from one structural form into another. Programming such deformation properties into the structure is often challenging and in…
Blended Cured Quasi-Newton for Geometric Optimization
Yufeng Zhu, Robert Bridson, Danny M. Kaufman
Optimizing deformation energies over a mesh, in two or three dimensions, is a common and critical problem in physical simulation and geometry processing. We present three new impro…
Geometric Numerical Integration of Inequality Constrained, Nonsmooth Hamiltonian Systems
Danny M. Kaufman, Dinesh K. Pai
We consider the geometric numerical integration of Hamiltonian systems subject to both equality and "hard" inequality constraints. As in the standard geometric integration setting,…
